Colgate coach Emmett Davis came out of the visitors’ locker room at the Carrier Dome, his face slightly ashen, and offered a subtle shake of the head.

Davis had just watched as the eighth-ranked Syracuse Orange delivered a 100-43 thumping of his Colgate Raiders in front of 21,247 fans at the Dome on Saturday night.

“There’s not much to say,” Davis said. “We’re not playing very well right now and they are. We’re not a very confident basketball team. They just took our heart away in the first five minutes of the game.”

Syracuse jumped on the Raiders early, roaring out to leads of 12-0, 17-2 and 34-4.

Since Syracuse and Colgate first met on the hardwood back in the 1901-02 season, the two Upstate New York schools have played 163 games. Syracuse has played more games against Colgate than any other school.

But never in the history of the series has a game been as lopsided as this one. Syracuse led by as many as 63 points. The 57-point final equaled the largest margin of victory in Syracuse coach Jim Boeheim’s 35-year tenure at SU. Syracuse beat C.W. Post 129-72 in the 1989-90 season.

“They’re struggling and they really struggled tonight,” Boeheim said. “They had some open shots early and they just didn’t go down for them. They had a bad night.”

Syracuse beat Colgate for the 45th consecutive time. The Raiders’ last win over SU came in the 1961-62 season.

It was the largest margin of victory for Syracuse since a 127-67 win over American on Dec. 2, 1964. Boeheim was a junior at Syracuse that year.

Syracuse ran its record to a perfect 10-0 for the season. Colgate fell to 0-8. One of Colgate’s losses was a 110-58 setback at No. 1 Duke on Nov. 19.

“We competed much better in the Duke game,” Davis said. “It’s not about Syracuse or Duke. It’s about us. We went in 9-8 at the first media (timeout at Duke). It was 20-12 after two (timeouts). They had a big run in the second half and pulled away, but we battled the whole game. That wasn’t the case tonight.”

Syracuse forward Rick Jackson registered his eighth double-double in 10 games this season with 18 points and 10 rebounds. Freshman Dion Waiters scored 17 points off the bench. Brandon Triche went 3-for-5 from 3-point range as he finished with 14 points.

Triche, who had not made a 3-point shot since SU’s game against Detroit on Nov. 11, made his first two attempts from beyond the arc. He had missed his previous 13 attempts from the 3-point line.

“I think the second one felt better,” Triche said. “If the first one didn’t go, I probably wouldn’t have felt as confident for the second one. Seeing the ball go through probably raised my confidence 30 percent.

“Just to hit a three and know what it felt like again,” Triche added, “that felt great.”

The Raiders attempted 28 shots in the first half and made three. Colgate missed all six of its 3-point attempts in the opening half, and Syracuse took a 46-8 into the halftime break.

Colgate’s futility established a Carrier Dome record for fewest points in a half. The previous low was held by Princeton, which scored 11 first-half points against SU on Nov. 12, 1999.

Colgate did manage to avoid breaking the Dome record for fewest points in a game. That record was set in a 58-35 SU win over Colgate on Dec. 10, 2005.

Syracuse, which had been struggling all season to make shots from outside the 3-point line, made a season-high 11 3-pointers against the Raiders. The Orange went 7-for-14 from 3-point range in the first half and finished the game 11-for-25 from outside the arc.

“Tonight, we made shots and they didn’t,” Boeheim said. “When that happens, it gets out of hand. If they had made some shots and we’d missed some shots — we were 7-for-14 from the three. If we’re 2-for-14 like we usually are and they make three or four threes, it’s a 20-point or 15-point game.”
